- setup and operate without need of a PC
Phone call, SMS and Email alert system
The system can be connected to auxiliary devices for generating Phone call, SMS and Email alerts. The alerts will be delivered for both high and lower temperature limits. The delay duration also can be programmed.
Features of Alert System:
- Phone calls can be made to upto 8 operators. Upon attending the phone call, a recorded voice message can be head indicating the nature of the fault
- SMS alert can be delivered fo rupto 8 operators. The SMS message will indicate the locati
on and nature of the fault. - Email alerts can be delivered to 4 email ids. The Email will indicate the exact temperature at the time of occurrence of the alert.
- Please see videos of the monitoring and alert system
